I have found accelerometer mouse that uses the accelerometer for both but I need one that uses, change in direction - to move the mouse left and right , tilt (top/bottom) for up down. I was thinking that someone handicapped could use a phone mounted on a hat to move the mouse up/down, left right. (select can be done via another program that uses voice.) BTW, I want to send the signal to a computer the same way as accelerometer mouse. Thanks
